To all whont it may concern.-

Be it known thatI, JOHN GRIFFIN, machineband manufacturer of Cork, inthe county of Cork, Ireland, a citizen of the United Kingdom of GreatBritain and Ireland, have invented a certain new and Improved Method ofManufacturing Flat Woven Gut Belting, (for which I have obtained LettersPatent in Great Britain, No. 6,039, dated April 9, 1889;) and I dohereby declare that the following is a full, clear, and exactdescription thereof.

This invention has reference to improvements in the manufacture of gutbelting, whereby I am enabled to produce belts or bands of this materialof sufficient width and length for use in connection with flat pulleysor Wheels.

In carrying out my invention Iprepare, in

the first instance, suitable strands of gut byspinning on a wheel in theordinary Way; and I then take several of these strands, according to thethickness and strength of the belt to be made, and spin them into onestring or thread. The strands, strings, or threads thus prepared arethen strained and softened in water or oil until they are soft enough toweave close, when a sufficientnumber, according to the Width of belt tobe produced, is placed in the loom an d woven as close as possible bytwilling, (or tweeling,) or in any other suitable way found convenient.\Vhen the Weaving process is completed, the fabric is taken from theloom and dried, when it is ready for use.

Cotton, linen, jute, or other ordinary material may serve as the fillingor weft.

Having thus described the nature of my said invention, I would have itunderstood that what I claim is- The improved method of manufacturingflat 'woven gut belting, which consists in first spinning gut intothreads, then twisting together several of these threads into a compoundstrand, then straining the strands thus formed and softening the same inwater or oil, and finally weaving them as Warp into a fabric suitablefor .belting, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this23d day of July, 1889.

JOHN GRIFFIN.
